# Watteco Modbus

{% hint style="info" %}
Il faut au préalable configurer une ou plusieurs requêtes Modbus périodiques via downlink. Plus d'informations : <https://support.watteco.com/modbus/>

Dans l'ordre, il faut :

1. Configurer l'inetrface série (baudrate, parité, etc).
2. Configurer une requête Modbus sur un E*ndPoint*.
3. Configurer un envoi d'*uplink* à chaque réponse Modbus (suite à la requête).
   {% endhint %}

Il y a 10 *EndPoint* possibles sur les Watteco Modbus, le codec ne couvrent que les 4 premiers. Les requêtes ne peuvent pas excéder 16 registres. Chaque requête Modbus sera reportée dans la table Modbus du RX LoRaWAN comme suit :

{% code title="" expandable="true" %}

```
{
    endpointXSlaveID
    endpointXFunctionCode
    endpointXNumberOfRegisters
    endpointXExceptionCode
    endpointXRegister0
    endpointXRegister2
    ...
    endpointXRegister15
} 
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://enless.gitbook.io/centre-aide/ressources/gateway-lorawan/decodeurs-capteurs-tiers/watteco-modbus.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
